Program Title: Roger Shew, UNCW Professor, "Hidden Treasures and Uniqueness of Brunswick County”
Date/Time/Location: January 3, 2025, 10:00 a.m. @ St. James Community Center
Note: This was a combined program with all chapters.
SUMMARY:
Julie Wilkinson opened the meeting. All three chapters are full as of this meeting.
Speaker: Roger Shew, Lecturer on Geology and Environmental Science, UNCW
Professor Shew introduced his documentary, “Shew’s Natural Treasures”, by stating that there are many natural
treasures within, and within an hour’s drive, of St. James.
Documentary points:
Bodies of water:
Lake Waccamaw is NC’s largest lake.
The Black River is home to the oldest trees (Bald Cypress) in NC. It flows into the Cape Fear River.
In the Three Sisters Swamp there is a tree called BLK227. One tree, named BLK227, which dates
back beyond the year 600 B.C., makes it the fifth oldest tree in the world as of 2024.
The Cape Fear River is the main drinking water source for Brunswick County.
Cape Fear threats: sea level rising and chemical threats (PFAs)
“Carolina Bays” are a misnomer. They are actually lakes, many of which are protected. The were
called “bays” not for the type of body of water the were, but rather for the bay trees that surrounded
them.
Naturally-produced tannic acid is what darkens many of NC’s bodies of water.
Salt Marshes occur where fresh water and the ocean meet (estuaries).
Threat: Rising sea levels are outpacing the salt marshes ability to rise above.
Manmade oyster reefs are being built. They are great at filtering toxins out of the water.
Located along the Brunswick and Cape Fear Rivers is the town of Navassa, which has a rich cultural
heritage supported by strong roots in the Gullah-Geechee culture, a group of African Americans along
the southeast coast of the United States from Jacksonville, FL to Jacksonville, NC.
Trees:
32 species of longleaf pines exist in NC. From the 1700s to the 1870s, slaves worked the trees to
produce the resin, which was extremely important to the British Navy (“the Naval stores”). What
affects longleaf pines: fire; urbanization. Prescribed burns help keep longleaf pine communities
healthy and prevent wildfires. The pines wouldn’t exist without restorative fire, which burns away
competitive growth such as shrubs so native plants and grasses can germinate seeds. Fires are naturally
caused by lightning bolts. Native Americans used fire to drive prey.
The Green Swamp has four pine varieties.
Carnivorous plants:
36 types in NC
Venus fly traps, sundew, pitcher plants, butterworts
Venus fly traps #1 food is beetles, not flies
It is a Class H felony to poach Venus fly traps.
Blooming Venus fly traps have tall white flowers, typically in the last week of May through the first
couple of weeks in June Venus fly traps have no real predators, but occasionally you can observe some moth damage.
Barrier islands:
They are called barrier islands because they protect inlands from ocean waves.
NC is #2 in the country, second only to Texas, for barrier islands (18+)
Barrier island development (human) alters the natural process of nature.
Bald Head Island provides habitats for migratory birds and other animals, e.g. loggerhead turtles.
Rock outcropping:
At the south end of Kure Beach there are coquina (shell) outcroppings where you can see lots of
marine life.
End documentary followed by Q &A
All chapters met separately following the meeting.
